Stimulus

An energy change that effects an organism through its receptor cells.

Stimulus control

When the rate, latency, amplitude or duration of a response is altered in the presence of an antecedent stimulus.

Stimulus class

A group of stimuli that share specific common elements along formal, temporal and/or functional dimensions.

Conditioned stimulus (CS)

A formerly neutral stimulus that elicits respondent behavior only after it has been paired with an unconditioned stimulus or another conditioned reflex.

Discriminated stimulus

Stimulus in the presence of which responses of some type have been reinforced and in the absence of which the same type of responses have not been reinforced.

Unconditioned stimulus

A stimulus change that increases the frequency of any behavior that immediately precedes it.

Stimulus discrimination training

Responses are reinforced in the presence of the Sd but not in the presence of the S delta. The person will learn not to respond in the presence of the S delta.

Stimulus generalization

An antecedent stimulus consistently evokes a response because it has been reinforced; stimulus generalization occurs when UNTAUGHT stimuli that are similar to that taught stimuli, also evoke that response.

Feature stimulus class

Stimuli that share common physical forms or structures or relative relationships. "made from wood".

Contingency

Dependent and/or temporal relations between operant behavior and its controlling variables.

3-term contingency

Basic unit of analysis in the analysis of operant behavior.

Avoidance contingency

A contingency in which a response presents or postpones the presentation of a stimulus.

Escape contingency

Contingency in which a response terminates from an ongoing stimulus.

Reinforcer

A stimulus change that increases the future frequency of the behavior that precedes it.

Unconditioned reinforcer

Stimulus change that increases the frequency of behavior that precedes irrespective of the organisms learning history.

Unconditioned negative reinforcer

Stimulus change that functions as a negative reinforcer as a result of phylogeny, no prior learning.

Punisher

Stimulus change that decreases the future frequency of the behavior that precedes it.

Unconditioned punisher

A stimulus change that decresaes the future frequency of behavior that precedes it that is not paired with any other punishers, ex. pain, bad taste.

Positive punishment

A behavior is followed immediately by the presentation of a stimulus that decreases the future frequency of behavior.

Positive reinforcement

When a behavior is followed immediately by the presence of a stimulus that increases the future frequency of the behavior.
